The dramatic changes in the September 2001 data reflect the
impact of the terrorist attacks on Sept. 11, 2001, on aviation, including
several days in which commercial air operations were suspended.

The data reported here excludes small-certificated and commuter
carriers that began reporting T100 data in 2002 for comparability with
previous issues.
